64 bit?

Macs with Core 2 Duos or Xeon processors are 64 bit and Leopard has native 64 bit support, so there could be some performance gains by upgrading to Leopard assuming applications are written to take advantage of 64 bit processing, right?

Is there/will there be any way to take advantage of 64 bit processors in Max? What about any other popular audio software?

In light of David’s recent article on how Max 5, the fact that the core Max engine is largely based around code developed two decades ago for 32-bit processors, and also the fact that all the data-types are based on 32-bit types (int, float, symbol pointer), I don’t honestly see 64-bit making a lot of difference to Max 4.
